NFS: Mount option parser should detect missing "port="
The meaning of not specifying the "port=" mount option is different for "-t nfs" and "-t nfs4" mounts. The default port value for NFSv2/v3 mounts is 0, but the default for NFSv4 mounts is 2049. To support "-t nfs -o vers=4", the mount option parser must detect when "port=" is missing so that the correct default port value can be set depending on which NFS version is requested.
